During morning break, petite Aiko discovered a mysterious glowing gem hidden in the history classroom storage cabinet. As her fingers brushed it, a soft voice whispered in her mind, promising enhanced curves if she shared its power and then reclaimed it.

At lunch she let her best friend hold the gem briefly. The girl’s chest swelled from A-cup to B-cup while Aiko’s own breasts grew noticeably fuller in return. Craving more, Aiko passed the gem to her boyfriend Mako during history class. The moment he touched it, his body erupted with power. Muscles ballooned dramatically, shredding his shirt to reveal a sculpted eight-pack and massive shoulders. He shot upward in height as his pants ripped, his heavy flaccid bulge growing immense and resting across her desk with a heavy thud.

Aiko’s chest surged forward into bold, eye-catching proportions, stretching her uniform tight. The teacher, shocked, stormed over demanding to call the authorities. Thinking fast, Aiko snatched the gem back and pressed it into the teacher’s hand. The stone pulsed warmly as the teacher’s transformation began.
